The invention concerns a protocol for multiple access to a networked telecommunications channel. A current auxiliary terminal of a plurality of auxiliary terminals address reservation messages to a central terminal. The latter addresses to the current auxiliary terminal an allocation message of transmission capacity in terms of number of data packets of an information message of the current auxiliary terminal dedicated to another auxiliary terminal. The reservation messages are provided with an item of information relating to the number of data packets forming the information message of current auxiliary terminal, stored but not yet transmitted to the other auxiliary terminal, which are thus present between the last allocation message reception and the current reservation message transmission of given order, so that stability of the channel is improved.
